[RE-wrenches] Fronius IG4000 problem

[Larry Crutcher, Starlight Solar]

Wrenches,

A Fronius IG 4000 is doing some weird cycling. Every 45 seconds the  
voltage pops up to Voc and drops back to Vmp immediately followed by a  
downward ramp of voltage and corresponding rise in current. This  
repeats continuously. PV array Vsc is constant and all strings are +/-  
1 volt DC. I spoke with Dan at Fronius and they are working on it.  
BTW, very helpful and immediate response from Fronius.

Has anyone else seen this occur? This is the second problem with this  
inverter so I am wondering how Fronius is holding up for others.

Kindest Regards,
